Abstract
The utility model discloses a single-crystal copper enameled wire, which comprises a single-crystal copper conductor and an insulating varnish layer. The single-crystal copper enameled wire is structurally characterized in that the outside of the single-crystal copper conductor is uniformly coated with the insulating varnish layer. The insulating varnish layer is composed of an inner varnish layer, a self-adhesive layer and an outer varnish layer. The outside of the inner varnish layer is coated with the self-adhesive layer and the outside of the self-adhesive layer is coated with the outer varnish layer. According to the technical scheme of the utility model, due to the adoption of the single-crystal copper enameled wire, not only the characteristics of a common enameled round copper wire are enabled, but also the characteristics of better electrical transmission performance, excellent machining property, high strength, small diameter, environment resistance, insulating performance, good reliability and the like are realized. The single-crystal copper enameled wire belongs to the new material leading industry among seven national strategic emerging industries and can be widely applied to the fine coils of high-end electrical and electronic equipment, instruments and meters.
Description
Technical field
The utility model relates to a kind of enamelled wire, relates in particular to a kind of single crystal Cu enamelled wire.
Background technology
Winding wire is a kind of conductive metal wire with insulating barrier, and in order to coil or the winding of coiling electric and electronic product, it is done the time spent and produces magnetic field by electric current, or cutting magnetic line produces induced current, realizes the mutual conversion of electric energy and magnetic energy, so be called electromagnetic wire again.Winding wire is installed the features and applications of insulating barrier, can be divided into enamelled wire, lapped wire, extraordinary winding wire, inorganic insulation group line four big classes again, and the share that enamelled wire accounts in winding wire is maximum, and the annual annual requirement of China reaches the megaton level.Because in the manufacturing of making enamelled wire and later stage winding, plain conductor in the enamelled wire need bear high-intensity mechanical stretching and twisting, common metal is because factor manufacturings such as stretch-proof, tensile strength are very difficult, and the enamelled wire of its manufacturing defective also can't satisfy the needs of extraordinary Seiko electronic equipment because antifatigue, electrical conductivity poor performance, reliability be low etc.
Single crystal Cu is a kind of high purity oxygen free copper, and its whole copper bar only is made up of a crystal grain, do not have " crystal boundary " of intergranule, and single crystal Cu has excellent electricity and signal transmission performance, and has the surface quality of significant anti-fatigue performance and optics.
Summary of the invention
The purpose of this utility model is to provide a kind of single crystal Cu enamelled wire, and it has electrical communications and the processing characteristics performance is good, intensity and the high advantage of reliability.
The utility model is achieved like this, a kind of single crystal Cu enamelled wire, it comprises single crystal Cu conductor and insulation enamelled coating, it is characterized in that the single crystal Cu conductor evenly is enclosed with the insulation enamelled coating outward, the insulation enamelled coating is made of interior enamelled coating, self-adhesive layer and outer enamelled coating, interior enamelled coating is coated with self-adhesive layer outward, and self-adhesive layer is outward outer enamelled coating.
Technique effect of the present utility model is: the utility model not only has the plain edition enamelling cuprum round line, also have characteristics such as better electric transmission performance, good processing characteristics, high strength, fine line diameter, environmental resistance, insulation property, good reliability, new material guiding industry in the novel industry of country's 7 big brief biographies can be widely used in the fine coil in high-end electrotechnical, electronic equipment, instrument, the instrument.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of A-A cross section among Fig. 1.
Single crystal Cu conductor 2, interior enamelled coating 3, self-adhesive layer 4, outer enamelled coating in the drawings, 1.
Embodiment
As depicted in figs. 1 and 2, the utility model is achieved like this, it comprises single crystal Cu conductor 1 and insulation enamelled coating, its design feature is the single crystal Cu conductor 1 outer insulation enamelled coating that evenly is enclosed with, the insulation enamelled coating is made of interior enamelled coating 2, self-adhesive layer 3 and outer enamelled coating 4, the interior enamelled coating 2 outer self-adhesive layers 3 that are coated with are outer enamelled coating 4 outside the self-adhesive layer 3; The utility model is when transmitting signal, because conductor is single crystal Cu, reflection and the refraction of signal just can not take place in the characteristic of its no crystal boundary, the signal transitivity is good, single crystal Cu itself has good mechanical property, insulation enamelled coating outside single crystal Cu conductor 1 has three-decker, has improved anti-environment and the insulation property of enamelled wire, has also reduced the difficulty of processing of later stage winding.
